Cardiovascular system Flashcards
what are the components of the cardiovascular system?
Blood, heart, vascular system, and lymphatics
What are the functions of the cardiovascular system?
Transportation, regulation, and protection
what are the divisions of the cardiovascular system?
Systematic and pulmonary
T/F Both the lymph vascular system and blood vascular system are closed.
True
What is the difference between the systemic and pulmonary systems?
Systemic is blood flow between the heart and tissues, while pulmonary is between the lungs and heart
What is the difference between arteries and veins?
Arteries carry oxygenated blood to the body, with the exception of the pulmonary arteries
Veins carry deoxygenated blood and are thinner walled with lower pressure
What connects arteries to veins?
Capillaries (one cell thick)
Label the covered areas
Blue Aorta, green superior vena cava, purple pulmonary trunk, red right pulmonary arteries
Name the layers of the heart.
Pericardium, serous pericardium, myocardium, and endocardium
Don’t die yet, your pets won’t know where you went :(
What are the chambers of the heart called?
Atria and ventricles
Which ventricle is larger, right or left?
Left
Name the different types of valves.
Atrio-ventricular (mitral and tricuspid) in ventricles and semilunar between ventricles and arteries
Label the covered areas
Purple left atrium, blue right atrium, red left ventricle, green right ventricle
Which side of the heart holds deoxygenated blood?
Right
Which side of the heart pumps oxygenated blood?
Left
What is the difference between the cranial (superior) vena cava and the caudal (inferior) vena cava?
The cranial vena cava circulates blood from the head, neck, and forelimbs. The Caudal vena cava circulate from the trunk, pelvic, and hind limb regions
Where is the sinoatrial (SA) node located?
The right atrium
What does the atrioventricular (AV) node do?
The AV node receives impulses from the SA node
That is not me.
What is the bundle of His?
The bundle of His carries electrical impulses to the apical end of the left and right ventricles
T/F The purkinjie fibers carry electrical impulses to the apical end of the left and right ventricles
False. Purkinjie fibers carry electrical impulses up into the ventricular myocardium.
What is the equation for cardiac output?
Cardiac Output (Q)= Stroke volume x HR or Q=HR x SV
What is the percentage of blood compared to your body weight?
9%
Where does the majority of the blood in your body reside?
80% is found in the systematic system, and 20% in pulmonary system
Plasma is mostly made up of…?
Water 92%
